Hi Pete,

I get the same error - but this time the client-server traffic is a bit different (since the POST URI has change to http://[subdomain].blogspot.com:80/feeds/posts/full)

client:: GET http://beta/blogger.com/feeds/default/blogs (no credentials)

serv:: HTTP 401 (expected)

client:: GET http://beta/blogger.com/feeds/default/blogs (with auth)

serv:: HTTP 200 (got expected meta feed and from it got blog POST URI).

client: POST http://[subdomain].blogspot.com/feeds/posts/full (no credentials)

serv:: HTTP 401 (expected)

client: POST http://[subdomain].blogspot.com/feeds/posts/full (with auth)

serv:: HTTP 405 "HTTP method POST is not supported by this URL"

I use Charles and Etheral for debugging. I will email you the blog id (and the req content - in case its an err on my end).
